This event honors the twelve winners of the annual USA Mathematical Olympiad exam, the premier high-school level mathemati- cal problem solving competition in the United States. The two-day celebra- tion began with a sponsors’ reception at the MAA headquarters in its newly renovated Carriage House Conference Center. Representatives of the spon- soring organizations of the American Mathematics Competitions, along with members of the MAA Executive Com- mittee, were there to meet and greet the winners and their families. On Monday morning, the winners toured the Crypto- logic Museum at the National Security Winners of the USAMO.
